by accredited post-secondary institutions in the USA, it is allowed to remain active and operational. All .edu domain names registered before 2001 were grandfathered in, even if not an accredited USA post-secondary institution. According to the University of Oklahoma libraries, when interacting with Academia.edu, users should keep in mind that "you are not the customer," but rather "you are the product that these services seek to monetize and/or "offer up" to advertisers," that "you might be breaking the law," even if you are uploading your own work," and finally that "there are privacy implications," because a commercial site does not follow professional standards and "may share information about you". A critic, Kathleen Fitzpatrick, the director of scholarly communication at the Modern Language Association, said she found the use of the ".edu" domain name by Academia.edu to be "extremely problematic", since it might mislead users into thinking the site is part of an accredited educational institution rather than a for-profit company. Academia.edu claims it supports the open science or open access movements and, in particular, instant distribution of research, and a peer-review system that occurs alongside distribution, instead of before it. Accordingly, the company stated its opposition to the proposed (since withdrawn) 2011 U.S. Research Works Act, which would have prevented open-access mandates in the U.S. However, in the view of critic Peter Suber, Academia.edu is not an open access repository and is not recommended as a way to pursue green open access. Peter Suber instead invites researchers to use field-specific repositories or general-purpose repositories like Zenodo. In early 2016, some users reported having received e-mails from Academia.edu where they were asked if they would be interested in paying a fee to have their papers recommended by the website's editors. This led some users to start a campaign encouraging users to cancel their Academia.edu accounts. Other criticisms include the fact that Academia.edu uses a vendor lock-in model: "It's up to Academia.edu to decide what you can and can't do with the information you've given them, and they're not likely to make it easy for alternative methods to access". This is in reference to the fact that, although papers can be read by non-users, a free account is needed in order to download papers: "you need to be logged in to do most of the useful things on the site (even as a casual reader)". In December 2016, Academia.edu announced new premium
